Summary
This protein powder features high-quality whey protein isolate and partially hydrolyzed whey protein isolate, which are beneficial for muscle recovery and growth. However, the presence of sucralose, an artificial sweetener, and the use of both natural and artificial flavors detract from its overall health profile. The product is moderately processed, with a few additives, which impacts its score compared to cleaner protein formulations.
Key ingredients 5
Partially Hydrolyzed Whey Protein IsolateVery Good
Partially hydrolyzed whey protein isolate is a high-quality protein source with a complete amino acid profile. It is processed to enhance absorption and reduce potential allergens. This makes it an excellent choice for muscle recovery and growth.
Benefits
Provides a rich source of essential amino acids and supports muscle repair and growth.
Whey Protein IsolateVery Good
Whey protein isolate is a highly refined protein with minimal lactose and fat content. It offers a complete amino acid profile, making it ideal for muscle building and recovery. Its high bioavailability ensures efficient protein utilization.

Natural And Artificial FlavorBad
Natural and artificial flavors are used to enhance taste but can include a wide range of chemical compounds. The lack of transparency in their composition can be concerning for consumers seeking clean labels. They may also contribute to flavor addiction and desensitization.
Risks
Potential for allergic reactions and unknown long-term health effects due to undisclosed chemical components.
LecithinBad
Lecithin is used as an emulsifier to improve texture and mixability in products. It is often derived from soy or sunflower, which can be genetically modified. While generally recognized as safe, it is still a processed additive.
Risks
May cause allergic reactions in sensitive individuals and could be sourced from genetically modified crops.
Benefits
Improves product texture and mixability, making it easier to consume.
SucraloseBad
Sucralose is an artificial sweetener used to provide sweetness without calories. It is chemically altered to be non-caloric, but concerns exist about its impact on gut health and potential metabolic effects. It is a common alternative to sugar in low-calorie products.
Risks
May affect gut microbiota and has been linked to potential metabolic disturbances.
